Cisco Switching/Routing :: 3750x Stack - EIGRP Stub With Non-stub Neighbors
Sep 16, 2012
we have 5 sites connected with a combination of direct fiber and Service Provider Ethernet. The equipmet consists of 3750 stacks with IP Services. Currently each site runs full EIGRP and is a EIGRP neightbor to all the other sites. Everything is working fine right now.
We would like to upgrade the R5 site to a 3750x stack with IP Base (cheaper than IP Services) and configure it as EIGRP Stub. My concern is with the following statement in the IOS command reference guide.
Note Multi-access interfaces, such as ATM, Ethernet, Frame Relay, ISDN PRI, and X.25, are supported by the EIGRP Stub Routing feature only when all routers on that interface, except the hub, are configured as stub routers.

I have a 3560 with IP base that is acting as a true EIGRP stub router today. It advertises local routes to the upstream service provider router and receives a default route.
Now I want to connect a 3900 ISR as a voice gateway. The 3560 does not seem to be advertising any routes to the 3900. Ok the EIGRP stub doc says this:
Only specified routes are propagated from the remote (stub) router. The router responds to queries for summaries, connected routes, redistributed static routes, external routes, and internal routes with the message "inaccessible." A router that is configured as a stub will send a special peer information packet to all neighboring routers to report its status as a stub router.
# Any neighbor that receives a packet informing it of the stub status will not query the stub router for any routes, and a router that has a stub peer will not query that peer. The stub router will depend on the distribution router to send the proper updates to all peers.
I guess I don't understand why the stub advertises local routes to the upstream ISP router but does not seem to advertise routes to the 3900. Does the stub identify the ISP router as the distribution router somehow, thus differentiating it from the 3900? If so, how is this done?
show ip eigrp neighbor detail on the 3900:

I have A 3560x running 12.2(58)SE2 and jus tupgraded to IP services to allow Enhanced EIGRP as found on feature navigator. I need to run full EIGRP and disable Stub.
however, when I try to disable it, I get this error:
dist2-3560x(config-router)#do sho licenseIndex 1 Feature: ipservices Period left: Life time License Type: Permanent License State: Active, In Use License Priority: Medium License Count: Non-Counted
Index 2 Feature: ipbase Period left: 0 minute 0 second Index 3 Feature: lanbase Period left: Life time License Type: Permanent License State: Active, Not in Use License Priority: Medium License Count: Non-Counted
dist2-3560x(config-router)#no eigrp stub connected summaryEIGRP is restricted to stub configurations only on this platform.
I have installed the license and rebooted. by all indications th elicense is installed and should allow for Full EIGRP routing.

We have small which I'm looking to implement and have built this on GNS3.
We have:
Router A in site 1
Router B in site 2
Router C in site 3
Router A and B are connection via a point to point 100M link and from Router C we have a 2 point to point one of which is 5Mpbs and going to Router A and Router B.
For Router C to reach Router A network it will go via Router B and these are 100M connection. When the link between Router A and B goes down. Router C should update and start using the 5m route.
For some reson, the routes are not updating. I have to do 'clea ip eigrp ne' for the routes to update and if I reload the routers all works well, it seems the problem is intermittent.

I am looking to implement 25 Cisco 3750 switches with IPBASE image at the edge, across many cabinets. I understand I am limited to EIGRP Stub on the 3750 switches (with IPBase) and cannot acheive funding to upgrade to IPServices. Though I am not fully aware on the limitations, in terms of what I am trying to acheive.
Broadly speaking I want to install 2 x 3750 switches at the edge, with point-to-point links to two 6500 core switches (at the data centre) and then have HSRP interfaces on the 3750's, tracking the up links to the core switches. I am presuming this will be the best solution to ensure reliability.My 6500 switches run EIGRP and have many VLANs and other L3 networks advertised, which will need advertising to the 3750 switches. I would be looking to advertise two or three HSRP networks on the 3750 switches, up to the core switches.At the moment, the entire network is Layer 2 (VLANS + STP).
how to configure EIGRP across the 3750 switches and 6500 switches to allow for the 3750's to see the whole network and also advertise back up it's directly connected (HSRP) networks to the core. At the moment, after configuration, none of the switches see each other as EIGRP neighbours but can ping the L3 addresses on each end.

I can't seem to find where in ASDM (6.4.1), can we configure IGMP forwarding? ASA5520(config-if)# igmp forward interface outside The ASDM doc reference does not seem to be correct pointing to:configuring Stub Multicast Routing
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > Multicast > IGMP.
#Step 2 In the Multicast pane, check the Enable Multicast routing check box.
#Step 3 Choose MForwarding.
which generates:
ASA5520(config-if)# mfib forwarding

I'm swapping out a PIX, IOS 6.3 with an ASA 5520 v8. The PIX has the following 2 commands in it's config:
multicast interface outside
multicast interface inside
These commands do not exist on the ASA. I do not wish to enable multicast routing. What commands on the ASA are equivalent to the multicast commands on the PIX?

We are experiencing some issues with the Apple TV and WLC. We currently have a Apple TV and iPhone same sub net connecting via Lightweight AP (different sub net) which connects to a Cisco3750 running IP Base. This connects to WAN routers managed by third party over a WAN and connects to far end Managed routers, these connect to other Cisco3750 IP Base and onto a 2504 Wireless LAN controller. We have used the the following document for WLC configuration; [URL]
We turn on Multicast globally, with IGMP snooping enabled also enable Multicast Multicast under controller (only option available on 2504) and give the device M Cast address 239.21.1.150 . The P2P blocking action is disabled. Going to Monitor Multicast we can see the Report for 224.0.0.251 and MGID. However the issue is at the Sender Receiver side the iPhone cannot see the Airplay on the iPhone that should be seen if the end to end stream is working. My focus is now on the Cisco3750's, although I do not totally understand why the device needs Multicast enabled as the Multicast Join and Group Traffic is encapsulated in the CAP WAP Tunnel is it not? Anyway I have enabled the only option "ip multicast routing distributed" and under the V LANs that connect to WLC and AP the only option available is the "ip pim passive" there is no "ip pim sparese-dense mode"
I am sure the WLC is configured correctly, but I suspect that this will not work due to the IP Base image on the 3750's not being able to run full multicast or we need to use uni cast for this solution that the 2504 does not support.

I'm trying to review a QoS setup, and I'd like to make sure I fully understand the current setup before I change anything. I'm seeing output drops on two different queue-thresholds, but not sure how packets are making it to one of the queues.

I can find queue4-threshold3 in the mappings, but how are packets getting mapped to queue2-threshold1? The priority queue is disabled for this interface, so I'm not sure how this queue is dropping packets, according to the maps nothing is mapped to 02-01.

This 3750X stack (3 members) has some 100% cpu spikes. Is this bad enough to start tracking down the cause(s) or is this somewhat typical and not a reason for concern? I just took this reading. How can you detemine when the 100% and 80% spikes occurred?

I recently created a stack using (2) 3750x switches. I have three vlans on the stack (1,105,241) Vlan 105 is configured on 6509 core switches with multicasting and are connected to the stack via gigabit fiber. It is working well with clients on the Master or SW1, however clients on SW2 do not participate in multicasting Any client pc that is connected to SW2 vlan 105 does not show up in the "sh ip igmp snooping group" command. I can statically assign a client on SW2 to the mcast groups but but they fail to register on their own. I can take the cable connection from SW2 and plug it into an SW1 Vlan 105 port and it immediately becomes a member of the groups. I can then connect it back to the SW2 port and it disappears from the group membership. IGMP and PIM are configured with the defaults.

Seeing very high CPU on one of our 3750X stacks. Usally its around 30% but recently its 70, 80, 90 or maxed at 100% during the main day.IOS version c3750e-universalk9-mz.122-55.SE1.bin.Has a ten gig uplink connected to a nexus 7k and another ten gig connected to another 7k. Running Layer 3 and EIGRP on the 3750X.Is this normal for the CPU?

I have a stack of three 3750X-24P-S switches. Each switch has two PSU's.If I do a SH INVENT, switch 2 only lists Power Supply 0
If, however I do a SESS 2 onto the second switch in the stack and then do a SH INVENT, it shows both power supplies. Is it anything to be concerned about?

our WAN is connected via L2WAN and using EIGRP to connect the sites. Currently there are 35 EIGRP neighbors over L2WAN and we are to install 15 more sites and will be connected to the same L2WAN. Some sites are still using Cisco 2651XM and we would like to know if it can still handle another 15 EIGRP neighbors. Some sites are 2800 and 2900 routers. And is there any other things to consider for EIGRP over L2WAN?

I have two WS-C3750X-48PF-S in stack, but every one has just one power supply. In the package of the switches is included one stack power supply cable.does it make sense to use stack power cable if every switch has just one power supply ??

Switch 2 has an interface configured in RSU Standby.Switch 3 has an interface configured in RSU active. The upgrading sequence is : Switch 2, Switch 1, Switch3.The aim of the test is to prove that there is no loss of IP connectivity throught the RSU process.During the RSU process, there are ping between all the computers.
IOS starting version : 15.0-1.SE3
IOS upgrading version (with OVERWRITE) : 15.0-1.SE3 (same version)
1rst step : Switch 2 reboot and come back master but isolated from original stack (switch 1 and 3)
2nd step : Switch 1 reboot, and come back with switch 2 into the upgrading stack.
Issue : at this step :
- Switch 1 put its interface (IP 192.168.5.254) up :
- Switch 3 has not reboot and still has its interface (IP 192.168.5.254) up
=> we have some OSPF adjencies and mac flapping issues : switch 1 and 3 are trying to mount there OSPF adjencies on the same IP. We loss our IP connectivity since step 3 is not over.
3rd step : Switch 3 reboot and come back up in the upgrading stack. The IP connectivity is back, and the RSU process is done.Is that a normal behaviour ?How can we avoid to loose IP connectivity during RSU process ?

I've a situation where I need to add a new 3750x to a existing stack of 3750. [code] When I tried to stack them together, I get a version mismatch error. Is this because of the difference in SW Image? What are my options next ? My ultimate goal is to make the new switch stack correctly with the exisitng switches.

IOS upgrade tried on the stack of 2XWS-C3750X-24T-S , Upgrade was tried to support WCCP on the platform. Current version is Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 12.2(58)SE1, Not able find any IP Plus ios in the site ? Only available are IP base and Universal K9 , Tried upgrading to c3750e-universalk9-tar.122-58.SE2.tar by using stack upgrade method as per document [URL]
Upgrade fails with error :
%Error opening flash:update/info (No such file or directory)
ERROR: Image is not a valid IOS image archive.
Why current ios is not supporting WCCP , I hope it is there in the featureset. ( tried "sdm prefer routing" but no success) Does c3750e-universalk9-tar.122-58.SE2.tar will give me wccp support ? What is the issue with my upgrade and how do I do a successfull upgrade ?

We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high. This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure. Below I provided some outputs about how to diagnose it.

Our customer has a stack of 6 3750G switches. They want to add another switch to the stack. I tried to quote another G, but I got a warning that the G series is EOS January 30,2013. Can I add a 3750X to the stack? I know that no matter what switch I get, I will have to upgrade the IOS in the stack, as the stack is running 12.2(25)SEE2.

I have a 3750X 24 port switch (with NM-1G network module) running IOS 15.0(1). Is there any benefit or reason to plug in the included Stack Wise cable and loop it back to itself in a single switch installation?
I don't see any recommendation in the documentation. The data sheet indicates a single switch is a non-blocking device so I'd think there's no bandwidth advantage like there is when connecting an actual multi-switch stack and needing to close the loop for the full 32 Gbps stack bandwidth.

I have two 3750X in a stack. Each 3750X has one 10Gb uplink to primary core1 and one 1Gb uplink to backup core2 configured in 2 etherchannel groups. The member switch has bad ports, so I need to replace it. I have spare 3750X unit. Is it possible to connect the spare unit to the stack and then move the RJ-45 cables from the member with bad ports to the new member? That way I can minimize servers downtime to just a few seconds..If that would work, then the last step would be to move the 10Gb networking module from old member to the new one, as well as the secondary PSU. Is it doable? Also according to the documentation, all I need to add new member is matching IOS version, correct?

I have two 3750G switches stacked together however it's not in a full ring configuration:
Stack Ring Speed : 16G
Stack Ring Configuration: Half
Stack Ring Protocol : StackWise
And as shown below it's obvious which cable is not working:
show switch neighbors
Switch # Port 1 Port 2
-------- ------ ------
1 2 None
2 None 1
It's not flapping - it's like the cable isn't there at all. I'm going to try reseating the cable in there and perhaps an all out replacement if necessary. My question - is there any threat of a reboot of the switch stack or of partitioning of the switch stack by trying to get the 2nd cable working?
